ABSTRACT:
A process and apparatus are provided for producing polymerized plugs in which the polymerization starting materials are passed through heated reaction tubes by gravity feed. The polymerized rods so produced are cut into plugs and packaged for use. In an alternative embodiment, the polymerization starting materials are first encased within flexible sleeves, and the flexible sleeves are then passed through the heated tubes by gravity feed to form polymerized rods. Apparatus for performing the process includes at least one tube having an inlet opening and an outlet opening, the outlet opening being at a lower elevation than the inlet opening to provide for gravity feed through the tube, and structure to heat the tube. A cutting device cuts the polymerized rods into plugs as they exit the outlet opening.
